lSPECIFICATION forming part of Letters Patent No. 407,867', dated July 30, 1889.

Application filed August 13, 1888. Serial No. 282,537. (No model.)

.To all whom. it may concern.'

Be it known that I, EDWARD L. LIEDKE, a citizen of the United States, and a resident of Sandusky, county of Erie, and State of Ohio, have invented certain new and useful Improvements in Check-Punches, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The object of my inventionkconsists of the improvements hereinafter described and claimed.

Referring to the drawings, Figure l is a perspective view of the check-punch. Fig. 2 is a horizontal central section al view of the punch, certain portions being in plan. Fig. 3 isavertical central section of the punch. Fig. 4 is a detail view of the ratchet'and connections. Fig. 5 is a detail view of the check-holder. Fig. 6 is a perspective view of the punch with the front plates removed. Fig. 7 is a detail view ot' the punch and the male and female dies. Fig. S is a perspective view of the check-plate, a certain portion being broken away.

In the upper horizontal portion A of my punch I journal the vertical spindle B, that has its lower extremity b pivotally supported in the bracket b', that is secured to'the back wall of the punch. Integral with said spindle B are, respectively, the upper and lower sectors O O', the former carrying a series of punches c, that have vertically-sliding bearings in openings provided on the outer periphery of said sector. The lower extremities of said punches are respectively provided with male cutting-dies having the characters S l 2 3 4 5 6 7 8 9 0 on their faces c. These dies respectively interfit with the corresponding female dies c2, that are secured to the upper face of the sector O. Said punches are secured in position by means of set-screws e, that en gage with the vertical plain -faced slotted portions e3 of the punches. Said setscrews also act as stops engaging with the shoulder e of the punches and limit the downward movement of the same. Sector C is of greater thickness at vits outer edge, where the punches are inserted, in order to give increased bearing-surface for the punches.

Springs c2 have bearing at one extremity in the sector, and. at their upper extremity are inserted in openings respectively formed in the punches, and tend to elevate the punches when depressed. Pivoted at one extremity in lug f is the punch-actuating lever F, and work- .ing through an opening in the upper face of the machine and pivotally' connected with said lever F is the plunger f', inclosed at its upward pressure against the actuating-lever. The outer extremity of this actuating-lever is provided with finger-knobf. On either side of the spindle is pivoted the bifurcated rocking lever G, that is connected with the actuating-lever by link g, and at its opposite eX- tremity is loosely connected to pawl g', said pawl engaging at its lower extremity with ratchet-wheel g2, the latter being secured to shaft h, journaled longitudinally of the checkpunch. Said pawl is provided with a spring g3, that, together with the pawl, works through guide-sleeve g4 and causes the pawl to be in constant engagement with the ratchet. Cover g5 incloses the inner portion of the actuatinglever and connecting parts.

On the forward portion of the shaft h, intermediate of the sector O and the front wall of the punch, is the friction feed-rollerj, rigid with the shaft, and provided with a peripheral facej, formed of india-ru bber. Having bearing respectively on opposite sides of said roller is the bifurcated spring '72, which maintains said roller steady and prevents undue movement thereof. Face-plate K is provided with the feed-roller opening /t and the punch-opening k. tically to the front of the punch and provided with a vertical guideway l, in which is fitted shank l of check-holder Z2. Spring Z3 is also 'fit-ted in said guidcway, and exerts downward pressure on said check-holder. -The checkholder is provided with horizontal thumbpiece m, by means of which it may be elevated, and its foot portion is provided with the punch-opening m. Pivoted also in its against the friction-roller. To the upper extremity' of spindle B is attached knob n and index-finger n', the latter moving along the index-plate n? as the knob n. is turned.

lower portion is the idle-roller m2, that bears upper portion by spiral spring f2, that exerts A curved face-plate L is secured ver- IOO The operation of the punch is readily understood. The check-holder is raised by means of the thumb, and the check to be punched is inserted beneath the same. The force of the Spring presses the holder downward onto the check as soon as the hand is removed from the thumb-piece, and the checlr'is securely gripped between the, friction-roller and the idle-roller. The indeX-iinger is then turned over the proper character indicated on the index and the actuating-lever depressed, cutcarrier and a series of punches carried thereby, of pivotal punch-actuating lever F, and punch-engaging plunger f', pivoted to said lever, substantially as set forth.

2. The combination, with rotary vertical spindle B and sectors C C', rigid therewith,

said sector C carrying punches c, said sector C carrying dies c2, said spindle havingI at its upper end the handle u, of pivotal lever F, lug f, in which the latter is fulcrumed, plunger f', pivoted to said lever, and spring f2, substantially as set forth.

3. The combination, with rotary vertical spindle B, having knob n on its upper end, sector C, carrying punches c, and sector C', carrying dies c2, both said sectors rigid with said spindle, of lever F, plunger f', index-iinger n', rigidly secured to said spindle,'and indexeplate n2, substantially as set forth.

,4. The combination, with pivotal lever F, rocking lever'G, and link g, having its opposite extremities respectively pivoted to said two levers, of ratchet g', having its upper end pivoted to lever G by a joint which permits a certain independent play of said two parts, ratchet-wheel g2, shaft h, and feed-wheel j', substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 23d day of July, A. D. 1888.
